Backpack frame

Abstract

The backpack frame includes a substantially polygon main member with a set of horizontally-oriented-oval-shaped slots and a set of vertically-oriented-oval-shaped slots. At least some of the set of vertically-oriented-oval-shaped slots separate the horizontally-oriented oval-shaped slots. The substantially polygon main member includes a top end and a bottom end, the bottom end forming an obtuse angle with the top end, the bottom end including a set of mounting tabs disposed in a substantially perpendicular direction thereto. Each of the set of mounting tabs has a set of oval-shaped-slots and at least one circular slot. In one example the substantially polygon main member of the backpack frame has three top sides forming three sides forming a substantially octagon shape. Reinforcement brackets can be fastened by any fastening means to at least two of the three sides of the substantially octagon shape include a reinforcement bracket.

What is claimed is: 
     
       1. A backpack frame system comprising:
 a substantially polygon main member formed from a single piece of material with a set of horizontally-oriented-oval-shaped slots and a set of vertically-oriented-oval-shaped slots,
 wherein at least some of the set of vertically-oriented-oval-shaped slots separate the horizontally-oriented oval-shaped slots, the substantially polygon main member including a top end and a bottom end and a front side and a back side, the back side for securing loads, the bottom end forming an obtuse angle in a direction towards the back side with the top end, the bottom end including a pair of mounting tabs disposed in a substantially perpendicular direction thereto, each of the pair of mounting tabs with a set of oval-shaped-slots and at least one circular slot, 
 wherein the substantially polygon main member has a first back side, a first back top side, a second back top side, a third back top side, and a second back side which together form five sides of substantially octagon shape and each of the first back side, the first back top side, the second back top side, the third back top side, and the second back side include a rolled edge that is bent in a direction towards the back side and defines a first gap between the first back side and the first back top side, a second back gap between the first back top side and the second back top side, a third gap between the third back top side and the second back top side, and a fourth gap between the third back top side and the second back side; and 
 
 an auxiliary substantially rectangular member with a set of horizontally-oriented oval-shaped slots and a set of vertically-oriented-oval-shaped slots, wherein at least some of the set of vertically-oriented-oval-shaped slots separate the set of horizontally-oriented-oval-shaped slots, the auxiliary substantially rectangular member including a side tabs disposed in a substantially perpendicular direction thereto, each of the side tabs with a set of oval-shaped-slots and at least one circular slot disposed in pattern to axially align with at least one of the set of oval-shaped-slots and the circular slot of the pair of mounting tabs so when mounted it can swing through approximately a ninety degree rotation. 
 
     
     
       2. The backpack frame system of  claim 1 , wherein two of the first back top side and the third back top side of the substantially octagon shape each include a reinforcement bracket. 
     
     
       3. The backpack frame system of  claim 1 , wherein the auxiliary substantially rectangular member is composed of metal, composite, plastic, or a combination thereof. 
     
     
       4. The backpack frame system of  claim 1 , wherein the substantially polygon main member is composed of metal, composite, plastic, or a combination thereof. 
     
     
       5. The backpack frame system of  claim 1 , further comprising:
 a first reinforced side support mechanically fastened to one of the pair of mounting tabs and a second reinforced side support mechanically fastened to another of the pair of mounting tabs. 
 
     
     
       6. The backpack frame system of  claim 1 , wherein at least two out of the set of horizontally-oriented-oval-shaped slots are larger than the others in the set of horizontally-oriented-oval shaped slots and include reinforcement guides to surround the two out of the set of horizontally-oriented-oval shaped slots which are larger. 
     
     
       7. A backpack frame system comprising:
 a substantially polygon main member formed from a single piece of material with a set of horizontally-oriented-oval-shaped slots and a set of vertically-oriented-oval-shaped slots, 
 wherein at least some of the set of vertically-oriented-oval-shaped slots separate the horizontally-oriented oval-shaped slots, the substantially polygon main member including a top end and a bottom end and a front side and a back side, the back side for securing loads, the bottom end forming an obtuse angle in a direction towards the back side with the top end, the bottom end including a pair of mounting tabs disposed in a substantially perpendicular direction thereto, each of the pair of mounting tabs with a set of oval-shaped-slots and at least one circular slot, 
 wherein the substantially polygon main member has a first back side, a first back top side, a second back top side, a third back top side, and a second back side which together form five sides of substantially octagon shape and each of the back side, the first back top side, the second back top side, the third back top side, and the second back side include a rolled edge that is bent in a direction towards the second back side and defines a first gap between the first back side and the first back top side, a second gap between the first back top side and the second back top side, a third gap between the third back top side and the second back top side, and a fourth gap between the third back top side and the second back side, 
 wherein two of the first back top side and the third back top side of the substantially octagon shape each include a reinforcement bracket, and 
 an auxiliary substantially rectangular member with a set of horizontally-oriented oval-shaped slots and a set of vertically-oriented-oval-shaped slots, wherein at least some of the set of vertically-oriented-oval-shaped slots separate the set of horizontally-oriented-oval-shaped slots, the auxiliary substantially rectangular member including a side tabs disposed in a substantially perpendicular direction thereto, each of the side tabs with a set of oval-shaped-slots and at least one circular slot disposed in pattern to axially align with at least one of the set of oval-shaped-slots and the circular slot of the pair of mounting tabs so when mounted it can swing through approximately a ninety degree rotation. 
 
     
     
       8. The backpack frame system of  claim 7 , wherein the auxiliary substantially rectangular member is composed of metal, composite, plastic, or a combination thereof. 
     
     
       9. The backpack frame system of  claim 7 , wherein the substantially polygon main member is composed of metal, composite, plastic, or a combination thereof. 
     
     
       10. The backpack frame system of  claim 7 , further comprising:
 a first reinforced side support mechanically fastened to one of the pair of mounting tabs and a second reinforced side support mechanically fastened to another of the pair of mounting tabs.
